Abstract
Photocatalytic treatment of aqueous cyanide was studied using both commercial and home-made $TiO_2$'s as catalysts. Among the catalysts, $TiO_2$ made from $Ti(OC_3H_7)_4$ as a precursor showed the highest activity for the degradation of cyanide exceeding a commercial catalyst of Degussa P25. The difference in activities of the catalysts was mainly related to the surface properties of the catalysts such as the ratio of acidic to basic hydroxyl groups. For the catalyst which showed the highest activity, partially reduced $TiO_2$ showed better activity than calcined one.
